CAMERA.

SPECIFICATION forming part of Letters Patent No. 764,910, dated July 12, 1904.

Application filed April 21, 1903. Serial No. 153,593. (No model.) 7

To all whom it may concern:

Be it known that I, FRANK A. BROWNELL, of Rochester, in the county of Monroe and State of New York, have invented certain new 5 and useful Improvements in Cameras; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and

I to the reference-numerals marked thereon.

My present invention relates to roll-holder cameras, in which an exposure is made upon a strip of sensitized material, such as film, extending in the focal plane of the lens and attached at its ends to rollers or spools; and my invention has for its object to provide a camera having a roll-holder and a support for the sensitized film, the parts of which are so arranged that the latter may be moved out of the focal 2O plane of the lens to allow the operator to focus the latter to produce a clear-cut and well-defined picture on the focusing-screen.

To these and other ends the invention consists in certain improvements and combina- 5 tions of parts, all as will be hereinafter more fully described,the novel features being pointed out in the claims at the end of the specification.

In the drawings, Figure 1 is a perspective 3 view of a camera constructed in accordance with my invention, showing the parts thereof detached. Fig. 2 is a side elevation, partly in section, showing the parts in their normal position. Fig. 3 is a similar view showing the film-support in the open position. Fig.

AL is a sectional view showing the sight-aperture. Fig. 5 is a plan view of the threading sheet or ,web.

Similar reference-numerals in the several 4 figures indicate similar parts.

I have shown my invention as applied to a folding camera embodyingthe body or box 1, provided with a drop front 2, as shown in Fig. 2, on which is supported the extensible frame 3, carrying the lens-mounting, and to which is also attached the forward end of the bellows 38, the opposite or rear end of which is attached to the bed 4. The latter is provided with the usual central aperture 5 and, if desired, the camera may be provided with the 5 usual or any preferred construction of plateholding devices, an illustration of which has in the present instance been omitted, as the present invention comprehends the application of a suitable roll-holder the parts of which are so arranged that it may be used in conjunction with such plateholding devices and also permitting the lens to be focused in the usual manner-,as will be further explained.

Arranged at one side of the camera box or body is a casing provided with the bottom 6,

front and rear walls 7 and 8, respectively, a top 9, and the ends 10, which latter are provided with suitable centering devices for the holding and windingspools. At one end is also 5 provided a suitable winding-key 11 for operating the receiving-spool, as shown in Fig. 1. Access may be had to the chamber in which the spools are contained by removing or opening the cover 9, which is hinged at one edge and se- 7 cured at the opposite side by means of springcatches 15, engaging suitable catch-plates in the cover, as shown in Fig. 4.. The cover is also provided with an aperture 16, beneath which extends a tube or well provided at its lower end with a covering of colored glass or similar transparent material 20, arranged to permit the operator to inspect markings or indications provided at intervals upon a strip of film or the usual opaque covering provided upon the latter. At one side of the casing is an extension 22, adapted to project over the rear end of the box or body and in the focal plane of the camera-lens. This extension is alsohollow, virtually forming a portion of 5 the chamber containing the film-spools, and arranged therein is a film-support over which the film is passed. This support is formed by a roller 23, located at the end of the ex tension, as shown in Figs. 2 and 3, and to 9 which access may be had through a slide or door 24. In order to utilize the space in line with the roller and between the forward and rear sides of the film and provided in the casing is a pocket 25, formed by parallel front and rear walls 26, forming a convenient receptacle in which the usual ground-glass focusing-screen 27 may be arranged when not in use, as shown in Fig. 2. In front of the film-support the casing is provided with an aperture 30, adapted to register with the aperture 5 in the camera-bed 4, whereby the sensitized film may be acted upon by the rays of. light admitted to the interior of the camera. The edges of this aperture are slotted, as at 31, for the reception of a laterally-movable closure or slide 32, and as the latter is withdrawn when the film-support is in the operative or picture-taking position I provide a suitable holder or pocket arranged in the rear wall of the casing and indicated by 33, in which the slide may be held when not in use.

The casing containing the holding and receiving spool may be formed integrally with the camera-body 1; but as it may also be made removable I haveillustrated the parts as capable of detachment. Suitable connections between the casing and camera body are employed to secure the roll-holder and camera body together, and in the present instance these consist of posts or studs 34, arranged at opposite ends of the bottom 6 of the casing and adapted to project through apertures 35 in the top of the camera-body. The lower end of the posts are provided with reduced portions or shoulders 36, and engaging therewith are catches or latch members 37 arranged within the camera-body, as shown in Fig. 4.

By making the casing removable the entire device may be detached from the camera-body to move the film-support out of the focal plane, permitting the ground-glass screen 27 to be placed in focusing position on the bed 4, where it is retained by small spring-catches 37. After this operation the screen maybe removed and the roll-holder applied in position. A preferable construction, however, is the one shown, in which the extension 22 is movably attached to the casing, as by a hinge 40, as shown in Fig. l, the proximate portions of the casing and extension being chamfered or cut away on diverging lines, as shown in Figs. 2 and 4, the joint between the parts being made light-tight by a flexible connection of leather or similar opaque material 41, which permits their relative movement, as shown in Fig. 3. In order to hold the film-support in the open position shown in said figure, I provide between the extension of the casing and the camera-body arms 42 and 43, jointed at 44 and provided with a stop 45 to limit their opening movement and hold the arms in alinement, as will be understood. At the bottom of the camera-body is provided a small spring finger or catch 46, adapted to engage the lower end of the extension 22 to retain it in the normal position.

In Fig. 5 I have illustrated the threading strip or web 50 corresponding to a portion of the sensitized film which is arranged around the guide or roller 23, with its ends extending into the spool-chamber. This strip has its ends 51 and 52 formed narrower than the body, the former being adapted to be connected to the winding-spool 53, while the latter is attached to the free end of the film or the covering therefor, which is mounted on the holding-spool 54. By this arrangement it will be seen that the operator is enabled to thread or lead the film around the support in the extension of the casing without difficulty. To this end the threading-strip may be applied to or formed directly on the rear end of the film, as shown in Fig. 5, the line of connection being provided with perforations whereby said strip, may be easily detached before removing the roll of exposed film from the camera. The threading-stripbeing drawn around the support at the end of each strip of film always leaves the device adapted for the reception of an unexposed roll, as will be understood; but if said strip is for any reason omitted the operator may open the door or slide 24 and readily guide the advancing end of another strip around the roller 23 and between the adjacent walls of the film-support and casing.
